Abstract
A measurement is presented of the inclusive production of charged and neutral mesons from nonresonant annihilation in the energy region near the resonance. The momentum distribution shows a large contribution at high momenta as expected for heavy quark production. Comparison of the spectrum with several phenomenological models is made. The relative yields of the and mesons indicate that the charm cross section is dominated by the contribution.
